Abstract (en)
[origin: EP2037218A2] The circuit (1) has a voltage regulator supplying a regulated voltage (Vreg) to a sensor interface (2), an analogue-digital converter (8) and a digital signal control and processing unit (9). A ratiometric unit i.e. analogue multiplier (5), is powered via an external supply voltage source (Bat) to supply an analogue output measurement signal (Sm) representative of a value of a measured physical parameter based on an analogue measurement signal (Vm), digital measurement signal (S-D) and a variation in a level of a supply voltage from the external voltage sources.
